ALFALFA-GII'IIING MACHINE.

To all 'whom 'it may @ennemi l Be it known that I, Dow L. ADELSPER- can, a citizen of the United States, residing at Springfield, in the county of Clark and State of Ohio, haveinvented certain new and useful Improvements in Alfalfa-CuttingMachines, of which the following is a specification. Y

My improvement relates to machines for cutting alfalfa. hay and similar articles.

My object is to construct the parts s o that the hay will becut-to proper lengths and thereafter choppedor comminuted as finely as possible and to this end I have found it desirable to so arrange t-he mechanismthat no stems or pieces of any length can interfere with the chopping operatlon. It is desirable to employ appliances for choppin this hay after it is partially cut so arranged that pieces of the stalks of the hay cannot get between the blades of the chopping appliance. By' reason of the fact that the screen is employed through which the com minuted particles ofhay must pass it is especially desirable that the particles' be chopped. up evenlyso that the screening operation will not be interfered with.

In the dra-wings Figure l isa transverse sectional view through the center of the machine. Fig. 2 is a detail view of the chopping mechanism. Fig. 3 is a detail view in section showing the screen and casing. Figs. 4 and 5 are detail views of a modification of the chopping mechanism.

Like letters of reference indicate like parts throughout the several views.l y

The main casing for the machine is indicated by the letter a and is comprised of ordinary stationary upright parts. a1 indi'-` cates an upper. frame for the feed rollers and cutter and this frame is bolted in any ordinary way to the stationary frame a. The feed rolls a2 and a3 are journaled in the upper frame a1 and are operated continuously in the ordinary way for feeding the hay to the cutter a4. The lower feed roller is preferably shown of the iuted feed type. I have shown a stationary cutting bar a5 between the two feed rolls which is secured in the ordinary way within the upper frame a1. The cutter a* is also liournaled within the upper frame and is revolved continuously by manual operating means or powerdriven devices so that it will rotate in the direction of the arrow. I have shown this cutter.

of the ordinary spiral type having a series of projecting arms which carry the cutting blades a During tie revolution of said cutter the hay is cut in short lengths by cooperation of the movable blades a and the stationary cutting bar a5, there being shown in Fig. l one of said blades diy in a position to cooperate with the `stationary bar ai to cut the hay. The hay after' being cut is carried by said cutter or impelled thereby to the opening in the bottoni of the stationary casing aat the. point indicated by a? and said hay then drops within the receptacle as which is formed 1n the stationary frame a and there is the usual form of hinged top a encircling said casing. 1 The chopping device Z) comprises a series of disk like blades securely fastened together on the shaft b1 and said chopping device is preferably connected by any ordinary connection with the operating device so that ity will rotate continuously and I have shown same adapted to rotate in a direction reverse to that of the cutter a. The circular blades are indicated by b2 (see Fig. 2) and between each pair of blades there is a washer b, and a bolt b4 securely fastens the washer and blades to the body portion b5, the chopper and these blades are preferably circular and are formed with cutting teeth somewhat in the nature of saw te'ethon the periphery of thel blades thereof.

In Figs. 4 and 5 I have shown a modificationof this chopper device whereby I dispense with the circular disk-like blades and instead thereof use fiexible hinged blades sc cured to the body portion of the chopper somewhat in the 4same mannerl as shown in Fig. 2.

The screen b is placed on the bottom of the receptacle a8 and same is secured to the bottoni of the receptacle by means of bars?)7 Patented Aug. 31, 1909.

which project above the bottom of the re- Ceptacle and cooperate with the teeth on the blades b2 for the purpose of cutting the hay intov small particles. I have shownthese cutter bars 227 attached to the casing a by bolts (see Fig. 3) bs counter-sunk therein. As shown in Fig. 1 these cutter bars b7 are spaced at intervals so that there are shown in fact live cutter bars which coperate with the teeth formed on'the disk b2 for thevpurpose of yconnninuting the hay into small particles.

planes move from side to side.

'ing the blades b2 It is apparent thatthe chopping device is I so arranged that the hay will be carried or impelled around the receptacle until it is reduced to particles suflicient to pass through the screen bf.

I have shown the chopping device so arranged that the blades b2 have a wabble movement, which is accomplished by placat an inclination out of the true vertical plane of rotation so that during the rotating movement of the disk their This is especially desirable in this class of machinery because getting within the spaces between Vthe cutting blades and thereby interfering with the operation ot' the machine.

llaviug described my invention, I claim as follows vice, and a the wabbling motion of the. disk will prevent the stems or straws of^hay.

2. In a machine of the character mentioned, the coinbiliatioii of a cutting device with a chopping device located in proximity to said cutting device, a receptacle partially inclosing said chopping device, a screening device located at the bottom of Said receptacle, a plurality of stationary blades spaced at intervals and projecting above said screening device, substantially as specitied.

In testimony whereof, I have hereunto set my hand this 17 th day of March, 1908.
